In India, the problems of chronic hunger and malnutrition persist on a massive scale. The prevalence of malnutrition is one of the highest in the world, higher than in some very poor countries of sub-Saharan Africa. According to the 2007 Progress for Children Statistical Review by the United Nations Children's Fund, the proportion of underweight children below the age of five -- an indication of malnutrition -- was 28 per cent in sub-Saharan Africa and 42 per cent in South Asia (43 per cent in India).
